By the way, a workaround for CTAN could be to extract the files using 
unzip and zip them again using Info-ZIP zip (one of the "good zip 
programs" mentioned on that website).  The result will be a ZIP file 
with text files flagged appropriately.  Just saying.

Actually its easier than that.  unzip -a (with end-of-line conversion) 
doesn't care for the actual format, it simply converts all occurrences 
of CR, CRLF and LF to the appropriate newline chars for the platform it 
is running on if the text flag is set.  Files with mixed line endings 
are normalized, i.e. they have a consistent end-of-line style afterward.

I'll send a first patch shortly.
